DeBeque Formation

The DeBeque Formation is a geologic formation in Colorado's Piceance Basin,[1] preserving fossils which date back to the Late Paleocene to Early Eocene period (Clarkforkian to Wasatchian in the NALMA classification.[2][3] Examples of these fossils are held in the University of Colorado Museum of Natural History.[4]
